Miley Cyrus kicked off the New Year Down Under, where she reunited with her former fiancé Liam Hemsworth and his family at the Falls Music Festival in Byron Bay. A source confirmed to E! News Sunday that Miley, 23, and Liam, 25, were seen "cuddling and kissing" at the concert, which they attended with the actor's brothers, Chris Hemsworth, 32, and Luke Hemsworth, 35, plus their wives, Elsa Pataky and Samantha Hemsworth. Another source described the exes as being "affectionate" in a VIP area: "Liam was seen rubbing Miley's back at one point."

Elsa posed for a picture with Miley, Samantha and a few other friends at the festival and shared it via Instagram Monday. "Me encanta la gente con la que me puedo volver loca./ I love people I can be crazy with!!" the Spanish star wrote in the caption. "@mileycyrus @martamilans @gisellamarengo #michele #samhemsworth @fallsfestival #bestfriends #fun #music #festival #falls."

The actress also gave her husband, Chris, a sweet kiss during the show. "Great night at the falls festival," she wrote in the Instagram caption. "Disclosure was amazing!" Liam, meanwhile, did not appear in any of his sister-in-law's photos.

Before she attended the festival Sunday night, Miley browsed the racks with Elsa and her girlfriends at Spell & the Gypsy Collective, where the women posed for a picture. "Nothing like a girly shopping mission when you're on vaycay ~ especially when it's festival-prep," the store wrote in an Instagram caption. Elsa, who married Chris in 2010, even mimicked Miley by sticking her tongue out for the sassy shot.

Miley also posed for a picture with one of Elsa's good friends, Gisella Marengo. "...so of course @melcarrero_ had to..." Spell & the Gypsy Collective wrote in the Instagram caption. The Byron Bay-based store shared yet another shot of the group of girls via social media, writing, "You could spot that tongue anywhere right?! Had a visit from babe'n @mileycyrus and @elsapatakyconfidential ~ the gorgeous posse shopped up a storm for their #fallsfestival outfits!"

One of Elsa's friends, Marta Martita, shared a picture Monday that showed people lounging by the pool. "And... That's a wrap in paradise everybody," she wrote in the Instagram caption. "Happy 2016 and thank you sister @elsapatakyconfidential and @chrishemsworth for being the best hosts ever.. Love you !!!"

It seems Miley is getting on well with those close to Liam—but what does it mean for their future? After calling it quits in 2013, both stars have professed that they will always love each other. And, as Liam told Men's Fitness in November 2015, he doesn't regret a moment of their time together. "You fall in love with who you fall in love with; you can never choose. I guess some people just come with a little more baggage," the Independence Day: Insurgence star said with a laugh. "I mean, look—we were together five years, so I don't think those feelings will ever change. And that's good because that proves to me that it was real. It wasn't just a fling."

He added, "It really was an important part of my life and always will be."
